In this paper, it is investigated whether an implicit evaluative-negative attitude towards back-stressing activities exists in pain-free subjects and in chronic low back pain patients. Using an affective priming task, it was investigated whether pictures of threatening back-stressing movements (primes) facilitate (respectively, slow down) the categorisation of subsequent evaluative-negative (evaluative-positive) words (targets). ⋯ In line with previous research, it is argued that this reverse priming effect is owing to the evaluative extremity of the primes: patients recognize the possibility that extreme primes will interfere with the categorisation of the targets and overcompensate for this possible effect. The implications for the prevention of negative attitudes towards back-stressing activities in non-clinical and clinical samples are discussed.

Ultrasonographic abnormalities detected in the sacroiliac area in twenty cases of upper hindlimb lameness.
The pelvis is covered with extensive musculature and often presents a challenge in diagnostic imaging. Ultrasonography provides diagnostic information about soft tissue, articular cartilage and bone surfaces, although little information exists about the normal ultrasonographic appearance of the equine sacroiliac region. ⋯ Diagnostic ultrasound is readily available to most practitioners. Therefore the findings of this study show that diagnosis of sacroiliac injuries is possible in the field.

A minimally invasive approach for posterior lumbar interbody fusion.
Despite the technical innovations that posterior approaches for lumbar fusion have undergone, the goal of a significant reduction in the extent of dissection has remained elusive. Because extensive muscular dissection is related to both acute and chronic pain, a reproducible minimally invasive posterior approach to lumbar interbody fusion would have significant clinical value. The technical aspects of a minimally invasive approach to posterior lumbar interbody fusion (microPLIF) with fixation involving tools developed for videoscopic discectomy will be described. ⋯ This procedure involves a reproducible technique that results in a construct that is radiographically identical to that which could be expected from any standard open procedure. The minimized muscular dissection results in a tremendous improvement in postoperative mobility. All complications in this series were related to the placement of femoral cortical allograft implants. The use of a modified cement restrictor should eliminate the risk of interbody device placement.
